Linux From Scratch - Version 7.0-rc1

Preface

vii. Host System
Requirements

Your host system should have the following software with the minimum
versions indicated. This should not be an issue for most modern Linux
distributions. Also note that many distributions will place software
headers into separate packages, often in the form of
“<package-name>-devel”
or “<package-name>-dev”.
Be sure to install those if your distribution provides them.

Earlier versions of the listed software packages may work, but has
not been tested.

Bash-3.2 (/bin/sh
should be a symbolic or hard link to bash)

Binutils-2.17
(Versions greater than 2.21.1a are not recommended as they have
not been tested)

Bison-2.3
(/usr/bin/yacc should be a link to bison or small script that
executes bison)

Bzip2-1.0.4

Coreutils-6.9

Diffutils-2.8.1

Findutils-4.2.31

Gawk-3.1.5
(/usr/bin/awk should be a link to gawk)

Gcc-4.1.2
(Versions greater than 4.6.1 are not recommended as they have
not been tested)

Glibc-2.5.1
(Versions greater than 2.14 are not recommended as they have
not been tested)

Grep-2.5.1a

Gzip-1.3.12

Linux
Kernel-2.6.22.5 (having been compiled with
GCC-4.1.2 or greater)

The reason for the kernel version requirement is that we
specify that version when building glibc in Chapter 6 at the recommendation
of the developers.

If the host kernel is either earlier than 2.6.22.5, or it was
not compiled using a GCC-4.1.2 (or later) compiler, you will
need to replace the kernel with one adhering to the
specifications. There are two ways you can go about this.
First, see if your Linux vendor provides a 2.6.22.5 or later
kernel package. If so, you may wish to install it. If your
vendor doesn't offer an acceptable kernel package, or you would
prefer not to install it, you can compile a kernel yourself.
Instructions for compiling the kernel and configuring the boot
loader (assuming the host uses GRUB) are located in Chapter
8.

M4-1.4.10

Make-3.81

Patch-2.5.4

Perl-5.8.8

Sed-4.1.5

Tar-1.18

Texinfo-4.9

Note that the symlinks mentioned above are required to build an LFS
system using the instructions contained within this book. Symlinks
that point to other software (such as dash, mawk, etc.) may work, but
are not tested or supported by the LFS development team, and may
require either deviation from the instructions or additional patches
to some packages.

To see whether your
host system has all the appropriate versions, and the ability to
compile programs, run the following:
